Fictional Fans

I always have one primary fandom, which usually changes about 2 years after I run out of new canon, and then a 'harem' of secondary fandoms, which are my old primary fandoms. The main difference is basically just that I'm less discerning about the quality of fanworks (and other content) I consume for my primary fandom, and that my primary fandom is always buzzing around at the back of my brain while I need to be more active to be fannish about the secondary fandoms (revisiting the canon, for example).

My primary fandom at the moment is Capaldi-era Doctor Who, and my secondary fandoms are - in order of seniority - Babylon 5, The X-files, Buffyverse, and The Mentalist

(I have also had brief one night stands with other fandoms, such as Life on Mars, ER, Lord of the Rings and Heartbeat, where I read all the fic I can get my hands on in one weekend and then move on - this usually happens when I'm in-between primary fandoms)
